Subject: jump.c: Use rtx_sequence
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=33d9cde485f08edc7ada941aef9229312f38f8ed;p=gcc.git

jump.c: Use rtx_sequence

gcc/
2014-08-27  David Malcolm  <dmalcolm@redhat.com>

	* jump.c (mark_jump_label_1): Within the SEQUENCE case, introduce
	local "seq" with a checked cast, and use methods of rtx_sequence
	to clarify the code.
